How did we pick these?
We started inside Wimberley and worked outward, capping the list at about an hour's drive. Every entry had to be a place the public can actually swim, or in one case a place everyone expects to swim and cannot, which is worth saying out loud rather than leaving out.
For each one we checked the operator's own page for fees, hours and access rules, then cross checked against a second independent source: the Wimberley View for Blue Hole's 2026 pass prices, KUT and Texas Standard for the Jacob's Well closure, the San Marcos Record for the new Rio Vista entry fee, and Community Impact for the change in ownership at Five Mile Dam.
There are no partners, clients or sponsored listings on this page. Every entry is an editorial pick and nobody paid to be here.
Two things we cut. Anything on private land with informal access, because a swimming hole you reach by trespassing is not a recommendation. And any site where published day rates and hours disagreed so badly that we could not describe the pattern honestly. Where sources did disagree mildly, on Krause Springs admission and the Cypress Falls gate rate, we say so in the entry instead of picking a number and hoping.
Which ones need a reservation?
This is the question that ruins Hill Country swimming trips, so here it is in one place.
| Swimming hole | Booking | 2026 cost | Drive from Wimberley |
| Blue Hole Regional Park | Required, half day blocks | $15 adult, $10 youth | In town |
| Hamilton Pool Preserve | Required, every day | $8 adult plus reservation fee | About 45 min |
| Blanco State Park | Day pass requested ahead | $5 per person 13+ | About 30 min |
| Pedernales Falls State Park | Walk up, park pass advised | $6 per person 13+ | About 50 min |
| Krause Springs | None, first come | Around $10 adult | About 1 hour |
| Cypress Falls | None | Roughly $8 to $10 | In town |
| Rio Vista Park | None, gated summer weekends | $5 for out of area visitors 18+ | About 20 min |
| Five Mile Dam Park | None | Free | About 25 min |
| Jacob's Well | Hiking only, no swimming | Free | About 10 min |
The short version: if you are planning a week out, book Blue Hole. If you are deciding at breakfast, drive to Five Mile Dam or Cypress Falls.
What should you know before you go?
Go early or go on a weekday. Nearly every problem on this list, full lots, sold out blocks, a two hour wait at a gate, is a weekend problem between 11am and 3pm.
Water status is not the same as park status. Hamilton Pool closes swimming for bacteria and rain while the preserve stays open. Pedernales Falls allows swimming only in the marked stretch downstream of the falls. Jacob's Well is open every day and has been closed to swimmers for four summers running. In all three cases the park being open tells you nothing about whether you can get in the water.
Bring cash and water shoes. Krause Springs has long preferred cash at the gate, and the riverbeds at Five Mile Dam and Blanco are rock rather than sand.
Check flow after rain, and after no rain. Heavy rain closes river access and spikes bacteria counts. A long dry spell drops spring flow, which is exactly what has kept Jacob's Well shut since 2022.
Can you still swim at Jacob's Well?
No, and it is not a seasonal thing. Hays County has not permitted swimming there since June 2022, and as of September 2026 the listing still reads cancelled until further notice. The spring's flow has repeatedly fallen to zero under drought and aquifer pumping. It ran hard for a short spell after heavy rain in July 2026 and then receded again. Reopening would take sustained monthly rain plus a real drop in demand on the Trinity Aquifer, not one good storm.
The natural area itself is free, open daily and worth the trip for the trails. Just do not build a summer afternoon around getting in.
What should you do next?
If your date is fixed, open the Wimberley Parks page and buy a Blue Hole half day block now, before you book anything else. That single reservation is the hardest part of the day to get and everything else can be arranged around it.
If you are already in town and improvising, drive to Cypress Falls, call on the way, and have Five Mile Dam as the backup. Then build the rest of the day around the water, with a stop on the Wimberley Square and the rest of the town's attractions once you have dried off.
